MACHINE FOR REMUVING BRISTLES FROM SKINS OR HIDES.

Application filed Decembler 5, 1923. Serial No. 678,700.

To all whom t may concern:

Be it known that I, ARTHUR GUs'rAv fjnUMEn, a citizen of the GermanRepublic, and residing at Markranstadt, Germany,

5 have invented certain new and useful Improvements in a Machine forRemoving Bristles from Skins or Hides, of which the following is aspecification.

This invention relates to improvements in a machine for removingbristles from skins or hides, of the type in which the skin or hide isguided around a horizontally lo` cated stretching-board with pointedouter edge and is at the latter parted by rotary 15 brushes, so that thebristles project from the soft hairs of the skin or hide and can be cuto.

According to the invention, directly in front of the pointed outer edgeof the stretching-board a long narrow suction nozzle is mounted forstraightening the projected and mostly crooked bristles, so that allbristles can be cut off at the root.

The accompanying drawing represents a machine embodying the improvement:Fig. l is a sectional side view, and Fig. 2 is a plan view, of the same.

Around-the rotary shaft a and the stretching-board Z) a stepwise Vmovedendless rib- 30 bon d is led, which serves to iiX thereon the skin orhide o to be treated, the rotary nected with a suction blower through apipe o. The bristles straightened or erected by the suction air arewholly cut o" by the cutters 27, g. This being nished and the cuttersbeing retracted, a throttle-nap o controlling the bore of the nozzle fn,is closed by means of a crank fw and a rod g which are actuated from acam-disc m of the machine gearing. During the closing position of theflap fe: the skin or hide is advanced for a Jfurther step and againparted by the brushes e, f, whereupon the flap o is re-opened and thebristles are cut olif, and so on. Y

What I claim, is

In a machine for removing bristles from skins or hides, the combinationwith a rotary shaft, a horizontally located stretchingboa-rd having apointed outer edge, a stepwise moved endless ribbon led around saidshaft and board and ladapted to receive the skin or hide to be treatedthereon, and a pair of brushes, one above and the other below thepointed outer edge of said stretching-board; of a long narrow suctionnozzle directly in front of the pointed out er edge of saidstretching-board, and means to control the bore of said nozzle independence upon the advance of said endless ribbon ,f substantially asand for the purpose set forth.

In testimony whereof I have hereunto set my hand in t-he presence of twosubscribing brushes e, f above and below said stretchingwitnesses. boardserving to part the skin or hide.
